Design and manufacturing of resonance frequency detector for actuating resonant sensors

Nowadays, different sensors are widely used in many industrial purposes. Many types of sensors are changing the capacitance or the inductance of a circuit when a parameter such as distance, pressure, temperature, mass, humidity and so on is changed. Any change in inductance and capacitance also leads to change the resonance frequency of the designed proposed circuit. In this paper a circuit is designed and manufactured which can be able to find the resonance frequency of the circuit via an algorithm with high accuracy and fast response.
